Description

Technical Field

[0001] The invention belongs to the technical field of couplings, in particular to a coupling nylon rod baffle fixing structure. Background Art

[0002] The elastic pin coupling is a mechanical component used to connect two shafts to transmit torque. It is mainly composed of half-couplings, nylon rods, baffles and other components. Its function is to connect the driving shaft and the driven shaft so that they are in the same state of motion.

[0003] The existing coupling is used on the belt conveyor. First, the baffle is fixed on the motor output shaft and the shaft of the belt conveyor roller respectively. Next, one half-coupling is connected to the output shaft of the motor, and the other half-coupling is connected to the roller shaft of the belt conveyor. Subsequently, the positions of the half-couplings are adjusted so that the two half-couplings are in contact with each other, while ensuring that the holes for inserting the nylon rods therein are accurately aligned. In this aligned state, the nylon rod is inserted into the hole of the half-coupling. Finally, the connection between the baffle and the half-coupling is fixed by welding to ensure that the nylon rod will not fall off the coupling during the operation of the coupling.

[0004] There are still some problems in the use of existing couplings. During the long-term use of the existing couplings, the interaction between the motor and the belt conveyor will produce uneven force, which will cause vibration. This vibration increases the friction between the nylon rod and the inner wall of the coupling, aggravates the wear of the nylon rod, and requires regular replacement of the nylon rod. In the process of replacing the nylon rod, it is necessary to cut the welding points on the baffle by gas cutting, and then replace the nylon rod in the coupling, and weld the connection between the baffle and the coupling after replacement. This process is complicated and takes a lot of time.

[0005] To this end, the present invention provides a coupling nylon rod baffle fixing structure. Summary of the invention

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1

[0037] like Figures 1 to 10As shown, a coupling nylon rod baffle fixing structure described in an embodiment of the present invention includes a half-coupling 1, the half-coupling 1 is symmetrically arranged, a nylon rod 11 is clamped between the two half-couplings 1, a retaining ring 12 is slidably connected to one side of the half-coupling 1, and an anti-falling component is arranged outside the half-coupling 1 and the retaining ring 12. The anti-falling component fixes the retaining ring 12 on one side of the half-coupling 1 so that both ends of the nylon rod 11 are blocked by the retaining ring 12.

[0038] Specifically, there are still some problems in the use of the existing coupling. During the long-term use of the existing coupling, the interaction between the motor and the belt conveyor will produce uneven force, which will cause vibration. This vibration increases the friction between the nylon rod 11 and the inner wall of the coupling, aggravates the wear of the nylon rod 11, and requires regular replacement of the nylon rod 11. In the process of replacing the nylon rod 11, it is necessary to cut the welding points on the retaining ring 12 by gas cutting, and then replace the nylon rod 11 in the coupling, and weld the connection between the retaining ring 12 and the coupling after replacement. This process is complicated to operate and takes a lot of time.

[0039] Therefore, the present invention solves this problem by setting up corresponding structures. First, the retaining ring 12 is fixed on the output shaft of the motor and the shaft of the belt conveyor roller respectively. Next, one half-coupling 1 is connected to the output shaft of the motor, and the other half-coupling 1 is connected to the roller shaft of the belt conveyor. Subsequently, the positions of the half-couplings 1 are adjusted to make the two half-couplings 1 contact each other, while ensuring that the holes for inserting the nylon sticks 11 thereon are accurately aligned. In this aligned state, the nylon stick 11 is inserted into the hole of the half-coupling 1 so that it is located inside the two conflicting half-couplings 1. Finally, the retaining ring 12 is fixed to the half-coupling 1 by an anti-fall-off assembly, thereby ensuring that the nylon stick 11 will not fall off from the coupling during the operation of the coupling.

[0040] The present invention fixes the retaining ring 12 and the half coupling 1 through an anti-drop assembly, thereby avoiding the problem of cutting the welding points on the baffle by gas cutting during the process of replacing the nylon rod in the existing coupling and then replacing the nylon rod in the coupling.

[0041] like Figures 1 to 4 As shown, a circular hole is opened in the middle of the half coupling 1 in this embodiment, and the shape of the retaining ring 12 matches the shape of the half coupling 1.

[0042] Specifically, a circular hole is opened in the middle of the half coupling 1, so that the motor output shaft and the shaft of the belt conveyor roller can be clamped with the half coupling 1, and the position of the half coupling 1 can also be adjusted after clamping; the nylon sticks 11 are arranged in a circular array in the two half couplings 1, and the length of the nylon sticks 11 is the same as the depth of the hole after the two half couplings 1 are fitted together; the shape of the retaining ring 12 matches the shape of the half coupling 1, so that the retaining ring 12 conflicts with the two ends of the nylon stick 11, and then the nylon stick 11 is sealed in the hole after the two half couplings 1 are fitted together, to prevent the nylon stick 11 from falling off during operation.

[0043] like Figures 1 to 4 As shown, the anti-falling assembly of this embodiment includes a fixing plate 21, the fixing plate 21 is fixedly connected to the outer surface of the half-coupling 1, the outer surface of the retaining ring 12 is fixedly connected to a fixing plate 22, the fixing plate 22 and the middle part of the fixing plate 21 are slidably connected with a screw rod 23, one end of the screw rod 23 is threadedly connected with a nut 24, and a quick installation and disassembly assembly is provided on the nut 24, and the quick installation and disassembly assembly is used for quickly installing and disassembling the nut 24 on the screw rod 23.

[0044] Specifically, the fixing plate 1 21 and the fixing plate 2 22 are both distributed in a circular array on the outer surface of the half coupling 1 and the retaining ring 12. When the nylon stick 11 is inserted into the hole of the half coupling 1, the retaining ring 12 is fitted with the half coupling 1, so that the fixing plate 1 21 on the half coupling 1 and the fixing plate 2 22 on the retaining ring 12 are on the same horizontal axis. At this time, the screw rod 1 23 is passed through the middle of the fixing plate 1 21 and the fixing plate 2 22, and the nut 24 is tightened on the screw rod 1 23 through the quick installation and disassembly assembly, thereby fixing the retaining ring 12 and the half coupling 1, so that the two ends of the nylon stick 11 in the half coupling 1 are abutted by the retaining ring 12;

[0045] The present invention uses a threaded connection between the screw rod 1 23 and the nut 24, so that the fixed plate 22 on the retaining ring 12 is gradually driven to move toward the middle of the screw rod 1 23 as the nut 24 rotates toward the middle of the screw rod 1 23, thereby driving the retaining ring 12 to move together with the fixed plate 22, so that the two ends of the nylon rod 11 in the half coupling 1 are fixed by the retaining ring 12, thereby avoiding the problem of the existing coupling that, during the process of replacing the nylon rod, the welding points on the baffle need to be cut by gas cutting and the nylon rod in the coupling need to be replaced, thereby shortening the time spent on replacement, reducing the cost of replacing the nylon rod, and improving the working efficiency of the belt conveyor.

[0046] like Figures 1 to 4 As shown, in this embodiment, holes are opened in the middle of the fixing plate 1 21 and the fixing plate 2 22 , and the shapes of the holes on the fixing plate 1 21 and the fixing plate 22 match the shape of the screw rod 1 23 .

[0047] Specifically, the shapes of the holes on the fixing plate 1 21 and the fixing plate 2 22 match the shape of the screw rod 1 23 , so that the screw rod 1 23 can pass through the fixing plate 1 21 and the fixing plate 2 22 .

[0048] Embodiment 2

[0049] like Figures 3 to 10 As shown, compared with Example 1, another implementation of the present invention is:

[0050] like Figures 3 to 7 and Fig.10 As shown, the quick installation and disassembly component of this embodiment includes a resistance cap 31, a displacement hole 32 is provided on the outer wall of the resistance cap 31, a threaded ring 33 is fixedly connected inside the displacement hole 32, a screw rod 34 is threadedly connected inside the threaded ring 33, an end of the screw rod 34 close to the middle of the resistance cap 31 is slidably connected to a resistance block 35, a limiting groove 319 is provided on the top of the resistance cap 31, a guide rod 320 is fixedly connected to the top of the resistance block 35, and an end of the guide rod 320 away from the resistance block 35 is slidably connected in the limiting groove 319.

[0051] Specifically, the coupling vibrates during operation, and during long-term use, the nut 24 and the screw rod 23 are worn due to vibration. At the same time, the nut 24 is exposed to the air for a long time, which causes oxidation and rust, causing the nut 24 to get stuck on the screw rod 23.

[0052] At this time, the nut 24 is disassembled. After the nut 24 is clamped, the electric wrench is used to drive the nut 24 to rotate clockwise, so that the second screw rod 34 pushes the resistance block 35 to move toward the direction close to the middle of the resistance cap 31, and under the action of the second limit groove 319 and the second guide rod 320, the resistance block 35 is horizontally displaced until the resistance block 35 conflicts with the nut 24, so that the two ends of the nut 24 are cut off under the action of the resistance block 35. At this time, the nut 24 is driven to rotate in the opposite direction until the resistance block 35 is reset. At this time, the nut 24 is no longer clamped, and the resistance cap 31 is removed. At this time, the staff manually pushes the nut 24 to loosen the nut 24 from the cut-off position and then fall off the surface of the first screw rod 23;

[0053] The present invention rotates the screw rod 2 34 clockwise so that the screw rod 2 34 is displaced toward the middle of the half coupling 1 under the action of the threaded collar 33, and then the guide rod 2 320 slides in the limit groove 2 319 to cause the abutment block 35 to be horizontally displaced, so that the abutment block 35 abuts against the nut 24, and the nut 24 stuck on the screw rod 1 23 is cut off, and then the nut 24 is removed from the screw rod 1 23, thereby shortening the time spent on disassembling the stuck nut 24 and simplifying the operation.

[0054] like Figures 5 to 10 As shown, the quick installation and disassembly component of this embodiment also includes a second displacement hole 36, and the second displacement hole 36 is provided on the outer wall of the contact cap 31, and a movement rod 37 is slidably connected in the second displacement hole 36, and an arc block 38 is fixedly connected to one end of the movement rod 37 close to the middle of the contact cap 31, and a return spring 39 is fixedly connected between the side of the arc block 38 close to the movement rod 37 and the inner wall of the contact cap 31, and a guide groove 310 is provided at the top of the contact cap 31, and a guide rod 311 is fixedly connected to the middle of the top of the return spring 39, and a guide plate 312 is slidably connected to the top of the contact cap 31, and a guide groove 2 313 is provided on the guide plate 312, and the return spring 39 slides in the guide groove 2 313, and a limiting groove 314 is provided at the top of the contact cap 31 close to the outer wall of the guide plate 312, and a limiting block 315 is inserted in the limiting groove 314.

[0055] Specifically, when the nut 24 needs to be quickly installed and disassembled, the nut 24 is threadedly connected to the screw rod 1 23. At this time, the limit block 315 is first taken out, and then the guide plate 312 is rotated counterclockwise, so that the guide rod 1 311 drives the arc block 38 to move in the direction away from the middle of the interference cap 31 under the action of the guide groove 2 313 and the guide groove 1 310, and the movement rod 37 is displaced together with the arc block 38 and slides in the displacement hole 2 36. At this time, the reset spring 39 is elastically compressed, and then the screw rod 1 23 is passed through the middle of the interference cap 31 until the nut 24 conflicts with the inner wall of the interference cap 31. At this time, the guide plate 312 is loosened, and the arc block 38 begins to reset under the action of the elastically released reset spring 39 until the arc block 38 conflicts with the nut 24, so that the nut 24 is clamped;

[0056] At this time, the limit block 315 is inserted into the limit groove 1 314. If the limit block 315 is blocked by the guide plate 312 during the insertion process, the guide plate 312 is rotated clockwise until the guide plate 312 no longer blocks the limit block 315 from being inserted into the limit groove 1 314. After the limit block 315 is inserted, the limit block 315 is located between the outer walls of the guide plate 312, thereby fixing the guide plate 312. At this time, the guide plate 312 drives the abutting cap 31 to rotate, so that the nut 24 can be quickly installed or removed on the screw rod 1 23;

[0057] After quick installation and disassembly, repeat the above operation to remove the abutment cap 31 and prepare for the next work.

[0058] like Figures 5 to 10As shown, the screw rod 34 of this embodiment is symmetrically arranged, and the moving rod 37 is arranged in a circular array on the outer wall of the resistance cap 31. A spacing is set between two adjacent arc blocks 38, and the spacing between the two adjacent arc blocks 38 is located on the movement trajectory of the resistance block 35.

[0059] Specifically, the arrangement of the arc block 38 allows the nut 24 to be clamped more stably; the distance between two adjacent arc blocks 38 is located on the movement trajectory of the resistance block 35, so that the resistance block 35 will not collide with the arc block 38 when cutting off the nut 24.

[0060] like Figures 5 to 10 As shown, in this embodiment, the middle part of the top end of the resisting cap 31 and the guide plate 312 is provided with a circular limiting hole, and the circular limiting holes on the resisting cap 31 and the guide plate 312 match the shape of the screw rod 23.

[0061] Specifically, the circular holes formed on the abutting cap 31 and the guide plate 312 allow the screw rod 23 to pass through the circular holes during the process of quickly installing and removing the nut 24, so that the installation and removal of the nut 24 do not require changing the direction of the force transmitted by the electric wrench.

[0062] like Figure 5 , Figure 6 and Figure 8 As shown, in this embodiment, the top of the guide plate 312 is fixedly connected to a support rod 316, the end of the support rod 316 away from the guide plate 312 is fixedly connected to a transmission plate 317, and the middle of the end of the transmission plate 317 away from the guide plate 312 is fixedly connected to a transmission rod 318.

[0063] Specifically, when the guide plate 312 needs to be rotated, the transmission rod 318 is driven to rotate by an electric wrench, and then the guide plate 312 is driven to rotate by the transmission plate 317 and the support rod 316 .

[0064] The present invention rotates the guide plate 312 to drive the guide rod 311 to move, so that the arc block 38 clamps the nut 24 located in the middle of the interference cap 31, and inserts the limit block 315 into the limit groove 314 to keep the guide plate 312 and the interference cap 31 relatively fixed. At this time, the transmission rod 318 is rotated, and the interference cap 31 is rotated synchronously through the transmission plate 317 and the support rod 316, so that the nut 24 clamped in the arc block 38 is quickly installed and removed, avoiding the problem that the staff uses a wrench to install and remove the nut 24, which makes the operation complicated, improving the efficiency of installing and removing the nut 24, and further accelerating the efficiency of replacing the nylon stick 11.

[0065] like Figure 8As shown, the support rods 316 of this embodiment are arranged in a circular array on the guide plate 312 , and the support rods 316 are located on both sides of the second guide groove 313 .

[0066] Specifically, the length of the support rod 316 is longer than that of the screw rod 23, and the support rod 316 does not contact the guide groove 2 313. When the transmission rod 318 drives the support rod 316 to rotate, the screw rod 23 passing through the interference cap 31 and the middle part of the guide plate 312 does not interfere with the transmission plate 317, thereby ensuring the normal operation of the quick installation and disassembly assembly.

[0067] Working principle:

[0068] First, fix the retaining ring 12 on the motor output shaft and the belt conveyor roller shaft respectively. Next, connect one half coupling 1 to the motor output shaft and the other half coupling 1 to the belt conveyor roller shaft. Then, adjust the position of the half coupling 1 so that the two half couplings 1 are in contact with each other, and ensure that the holes for inserting the nylon sticks 11 thereon are precisely aligned. In this aligned state, insert the nylon stick 11 into the hole of the half coupling 1 so that it is located inside the two conflicting half couplings 1. Finally, when the nylon stick 11 is inserted into the half coupling 1 After the hole is formed, the retaining ring 12 is fitted with the half coupling 1, so that the fixing plate 1 21 on the half coupling 1 and the fixing plate 2 22 on the retaining ring 12 are on the same horizontal axis. At this time, the screw rod 1 23 is passed through the middle of the fixing plate 1 21 and the fixing plate 2 22, and the nut 24 is tightened on the screw rod 1 23 through the quick installation and disassembly assembly, so that the retaining ring 12 and the half coupling 1 are fixed, and the two ends of the nylon stick 11 in the half coupling 1 are resisted by the retaining ring 12, thereby ensuring that the nylon stick 11 will not fall off from the coupling during the operation of the coupling.

[0069] When the nut 24 needs to be quickly installed and removed, the nut 24 is threadedly connected to the screw rod 23. At this time, the limit block 315 is first removed, and the transmission rod 318 is driven to rotate by an electric wrench, and then the guide plate 312 is driven to rotate through the transmission plate 317 and the support rod 316;

[0070] When the guide plate 312 rotates counterclockwise, the guide rod 1 311 drives the arc block 38 to move away from the middle of the contact cap 31 under the action of the guide groove 2 313 and the guide groove 1 310, and the movement rod 37 moves together with the arc block 38 and slides in the displacement hole 2 36. At this time, the return spring 39 is elastically compressed, and then the screw rod 1 23 passes through the middle of the contact cap 31 until the nut 24 contacts the inner wall of the contact cap 31. At this time, the guide plate 312 is loosened, and the arc block 38 begins to reset under the action of the elastically released return spring 39 until the arc block 38 contacts the nut 24, so that the nut 24 is clamped;

[0071] At this time, the limit block 315 is inserted into the limit groove 1 314. If the limit block 315 is blocked by the guide plate 312 during the insertion process, the guide plate 312 is rotated clockwise until the guide plate 312 no longer blocks the limit block 315 from being inserted into the limit groove 1 314. After the limit block 315 is inserted, the limit block 315 is located between the outer walls of the guide plate 312, thereby fixing the guide plate 312.

[0072] At this time, the transmission rod 318 is driven to rotate by the electric wrench, so that the guide plate 312 drives the abutment cap 31 to rotate, thereby allowing the nut 24 to be quickly installed or removed on the screw rod 23;

[0073] Because the coupling vibrates during operation, wear occurs between the nut 24 and the screw rod 23 due to vibration during long-term use. At the same time, the nut 24 is exposed to the air for a long time, which causes oxidation and rust, causing the nut 24 to get stuck on the screw rod 23.

[0074] At this time, the nut 24 is disassembled. After the nut 24 is clamped, the electric wrench is used to drive the nut 24 to rotate clockwise, so that the second screw rod 34 pushes the resistance block 35 to move toward the direction close to the middle of the resistance cap 31, and under the action of the second limit groove 319 and the second guide rod 320, the resistance block 35 is horizontally displaced until the resistance block 35 conflicts with the nut 24, so that the two ends of the nut 24 are cut off under the action of the resistance block 35. At this time, the nut 24 is driven to rotate in the opposite direction until the resistance block 35 is reset. At this time, the nut 24 is no longer clamped, and the resistance cap 31 is removed. At this time, the staff manually pushes the nut 24 to loosen the nut 24 from the cut-off position and then fall off the surface of the first screw rod 23;

[0075] After quick installation and disassembly, repeat the above operation to remove the abutment cap 31 and prepare for the next operation.
